To all whom it may concern:

Be itulmo'wn that I, HERMANN J. So-HU- Bnn'r; a citizen of the United States of America coiinty of Bergen, State of New Jersey, have and useful Im'provements in Cast Walls for Buildings, of which the following is a Specification.

This invention has reference to novel cast walls of I It is the special object of my invention to produce cast double walls of buildmgs for so called cement houses and the like. These novel walls may be of various thickness relative to each other and there is a continuous air space of peculiar form between said walls for the purpose of retaining a relatively uniform tem erature within the house. Means are provi terial and integral therewith for strengthening and connecting them in a pecuhar nanner, and connectin members for the inner and outer wall an within the strengthening portions above mentioned while the corner of two adjoining walls is so constructed that it is relatively strong. 7

The frame houses heretofore built are relatively uncomfortable because the summer heat easily penetrates the wooden boards of same and the cold of the winter can not be kept out eifectively. These are great disadvantages, not to consider that wood is becoming scarce and substitutes for same must strengthening portions and connecting membe found. Furthermore brick and stone houses of present constructions consist generally of solid walls without a continuous air. space therein and thus are less desirable although they are more expensive.

The cement houses composed of my novel walls retain relatively uniform temperature winter and excellent insulator against heat and cold and dampness. Furthermore, houses composed 'of my novel cast walls are relatively cheap in comparison to the houses of present construction and more durable. By virtue of the construction of the novel walls with their bers each cast double truly represents a and a resident of Hackensack, in-the' ed in the walls of thesame ma-' single-wall with a continuous air space of peculiar shape therein. This has been primarily attained by providing on each inner and outer wall portion interior strengthening ribs so arranged that they overlap each other in successive castings in alternative order and the peculiar air space above mentioned is formed around same, all as will be fully described hereinafter with reference to the accompanying drawings in which:

Figure 1 represents part of a cast wall in horizontal section embodying in desirable form the present improvements. Fig. 2 is a vertical section on line 2, 2 of Fig. 1 and Fig. 3 is a like section-on line 3, 3 of Fig. 1.

Similar characters of reference denote like parts in all the figures.

The novel walls are cast between suitably supported wall molds and around peculiarly constructed cores within said molds for which I have filed application for Letters Patent of the United States the 27th day of April 1909, saidapplication bearing Ser. No.

492, 19?) and the present application is a division of the above identified application.

For practical reasons the walls are cast in separate vertical sections wherebythe peculiar correlation and location of the overlapping ribs results.

In the drawing, a represents the outer wall of a double or compound wall and b is its inner wall. For the purpose of strengthening the walls and connecting them, ribs are roduced on their inner sides. These ribs being produced simultaneously with the walls during the process of casting form an integral part of same. The strengthening ribs of one section or casting, say for instance the lower section, are located alternately and successively one on the outer wall then one on the inner wall and again one on the outer-wall and so on. As shown in Fig. 1 of the drawing the ribs cast'with the lower section of the wall a are designated by the reference character a and the ribs cast simultaneously on the correspondin 'section of the wall 6 are designated by' the reference character 6 These latter ribs are located alternately between the ribs a Adjoining the wall so far described, there is shown in Fig. 1 a like wall at a right angle thereto. It is composed of an outer wall a and an inner wall'b and the same kind of ribs a are cast with the wall a and the ribs 5 with the wall 6 in alternative and successive Order as above described. In this way an air space a of peculiar form is produced between the ou'ter and inner wall around the strengthening ribs, of serpentine shape.

Both walls are connected by a strong solid corner d preferably in the manner shown in Fig. 1. While the inner walls b, b retain their usual thickness at the pointof union the outer walls a, a are joined by the solid corner-d of relative large diameter whereby a very strong corner is formed which is partlcularl valuable in houses standing alone asis 0 ten the case with country houses or houses standin on the corner of a street when the who e block is built up-in city style. For the'purpose ofconnecting consecutive vertical castings or portions of the walls, iron rods e are placed in such places that same are located within the ribs of the wall when same have been cast. These rods extend vertically up beyond the first lower casting or portion of the walls and extend each into or through at least two vertical rib portions formed by different castings, as

shown in Fig. 3. Each rod e passes first through a rib of the outer wall then passes through a rib of the inner wall whereby both are effectively connected and setting toward one'another or separating from each other is prevented. To further connect the outer and inner walls oblong metal frames 7, preferably of wrought iron, are pressed into the top of the casting just produced, before same gets hard. These are embedded into the outer and inner wall so that the short sides of each frame cross each two ribs, as shown in Fig. 1. The second casting or adjoining higher portion of the walls is produced in substantially the same manner except to note that the ribs a of the outer wall a are formed in this portion above the ribs 6 of the inner wall I) and overlap same, as shown in Fi 1, while the iron rod e passes through the tab 6 and the rib a for the purpose above mentioned in addition to the connection made by the metal frames f. In like manner ribs 6 are formed on the inner wall '6 above corresponding ribs (1 of .the outer wall and overlapping same. Corresponding ribs a, I), areformed in the walls a', V,

The production of wall portions as above described is continued I until the desired -height of the -walls has been produced.

wall the airspace is formed around the ribs of the first casting in form ofa serpentine" .ing portions, as shown in Fig. 1. While the lower casting or section is formed around the whole cores the second section is formed on the corner with half cores only as indicated in Fig. 1. The third section is again formed as the first section and the fourth like the second and so on.

The walls are cast of cement or any other suitable and approved composition. Inthe accompanying drawing, walls are illustrated.

which represent 1n about one-eighth of the natural size, approximately a twelve inch double or compound wall with an air space between the outer and inner wall of about five inches in diameter. 'This is a convenient size for smaller structures such as cottages and the like. .For larger structures the walls may be increased in width. These cast double Walls are. further very well adapted for storage houses because not' only the material is an insulator against heat and cold but the continuous air space within the; wall with the airconstantlyretained therein greatly increases its insulating qualities. Further in my novel walls both the outer and inner wall bear the weight of the entire house because they are connected byv the overlapping ribs, accordingly the Wallsina y be relatively thin. 1

I claim as my invention:

1. A hollow cast wall for buildings comprising an outer and inner wall, composed 'of consecutive vertical sections, having each integral, vertical innerjribs terminating short of the opposite ribs, so cast, that the ribs of the successive casting overlap the ribs of. the lower casting for securely connecting both walls, and vertical rods or ties passing through two overlapping ribs.

2. Ahollow cast wall for buildings comprising an outer and inner wall, composed of consecutive vertical sections, havlng each integral vertical mner ribs termmatmg short of the opposite ribs, so cast, that the ribs of the successivecasting overlap the ribs of the lower casting for securely connecting both walls, vertical rods or ties passing through two overlapping'ribs, and horizontal frames in the top portion of each section crossing two ribs of one wall.

3. A hollow cast wall for buildings comprising an outer and inner wall, composed of consecutive vertlcal sect ons, havlng each integral vertical mner r bs each trapezo1dal in cross section, said ribs terminating short necting each two outer walls and free from of the opposite ribs, so cast, that the ribs of the inner wall.
